* Migrate from #ifndef guards to #pragma onceNathaniel McCallum2016-05-291-4/+1
| | | | | | | | | | | | Using a pragma instead of guards is easier to write, less error prone and avoids name clashes (a source of very subtle bugs). This pragma is supported on almost all compilers, including all the compilers we care about: https://en.wikipedia.org/wiki/Pragma_once#Portability. This patch does not change the autogenerated files: asn1/asn1c/*.h. Reviewed-By: Martin Basti <mbasti@redhat.com> Reviewed-By: Christian Heimes <cheimes@redhat.com>

* ipasam: use more restrictive search filter for group lookupSumit Bose2015-11-231-1/+3

* add one-way trust support to ipasamAlexander Bokovoy2015-07-081-21/+85
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When trust is established, ipasam module creates a number of objects in LDAP to represent the trust information. Among them, for one-way trust we create a principal named IPA$@AD where IPA is a NetBIOS (flat) name of the IPA forest and AD is a realm of the trusted Active Directory forest root domain. This principal is then used by SSSD on IPA masters to authenticate against trusted Active Directory domain controllers and retrieve information about user and group identities. FreeIPA also uses this principal's credentials to retrieve domain topology. The access to the keys of the principal should be well-protected. We only allow to retrieve the keytab for it for members of cn=adtrust agents group. This group is populated with host/ and cifs/ principals from IPA masters. Starting with FreeIPA 4.2 the group will also have host/ principals of IPA masters where no ipa-adtrust-install was run. To add them, run ipa-adtrust-install on the master which will be configured to be a domain controller (e.g. run Samba with ipasam), and specify --add-agents option to trigger activation of the interactive mode to specify which IPA masters to enable.

| | | | | | We don't store trust type, attributes, and direction for subdomains of the existing trust. Since trust is always forest level, these parameters can be added as defaults when they are missing.
* ipa-sam: report supported enctypes based on Kerberos realm configurationAlexander Bokovoy2013-09-201-12/+117
| | | | | | | | | | | | | | | | | | | We store Kerberos realm configuration in cn=REALM,cn=kerberos,$SUFFIX. Along other configuration options, this container has list of default supported encryption types, in krbDefaultEncSaltTypes.

* ipa-sam: do not modify objectclass when trust object already createdAlexander Bokovoy2013-09-201-41/+71
| | | | | | | | | | | When trust is established, last step done by IPA framework is to set encryption types associated with the trust. This operation fails due to ipa-sam attempting to modify object classes in trust object entry which is not allowed by ACI. Additionally, wrong handle was used by dcerpc.py code when executing SetInformationTrustedDomain() against IPA smbd which prevented even to reach the point where ipa-sam would be asked to modify the trust object.
* ipasam: add enumeration of UPN suffixes based on the realm domainsAlexander Bokovoy2013-03-291-11/+181
| | | | | | | | | | | | | | | | PASSDB API in Samba adds support for specifying UPN suffixes. The change in ipasam will allow to pass through list of realm domains as UPN suffixes so that Active Directory domain controller will be able to recognize non-primary UPN suffixes as belonging to IPA and properly find our KDC for cross-realm TGT. Since Samba already returns primary DNS domain separately, filter it out from list of UPN suffixes. Also enclose provider of UPN suffixes into #ifdef to support both Samba with and without pdb_enum_upn_suffixes(). Part of https://fedorahosted.org/freeipa/ticket/2848

* Recover from invalid cached kerberos credentials in ipasamAlexander Bokovoy2012-08-221-37/+77
| | | | | | | | | | | | | | | | When developing and testing in the same environment, multiple re-installs may be needed. This means previously issued and cached Kerberos credentials will become invalid upon new install. ipasam passdb module for Samba uses Kerberos authentication when talking to IPA LDAP server. Obtained Kerberos credentials are cached during their lifetime. However, the ccache is not removed automatically and if IPA setup is made again, cached credentials are used, only to discover that they are invalid. With this change invalid correctly obtained cached credentials are recognized and, if LDAP SASL bind fails, new credentials are requested from the KDC. https://fedorahosted.org/freeipa/ticket/3009
